I am attempting to help solve a friend's problem occurring with a 5-rail (O gauge/Standard gauge) loop of track on his layout. We are attempting to operate using Lionel's TMCC control with O gauge locos. They do not respond to the Cab 1 except for an occassional whistle. (The loco's lights flicker indicating a response to the Cab 1 commands but the engines will not move.) The sound comes on with track power-up, indicating they are not sensing a TMCC signal. The same TMCC command center operates trains normally on the layout's regular O gauge track and MTH locos operate normally on the 5-rail O gauge/standard gauge track. I am wondering if the extra rails on the 5-rail track are creating enough interference to cause the problem with the TMCC signal. We would appreciate any input you may have,
Thanks,
